METHOD OF TREATING SHINGLES Original application filed February 10, 1927, Serial No. 167,177. Divided and this application filedl'une 20, 1927. Serial No. 200,189. r

- shingles and more particularly to an improved method for weather-proofing shingles or like articles.

Heretofore it has been customary to" weather-proof shingles by dipping the shingles in a vat or container which contains stain or various weather-proofing materials. This has usually been done by hand, the operator grasping in one hand one-half of a bundle of shingles, and with the other hand dipping them into the vat and moving the shingles while thus being dipped in order to allow the stain or weather-proofing mate-- rial to penetrate to all parts of the surfaces of the shingles. In other treatments, the shingles have been placed in a vat having a rotatable table or the like and the stain ap-- plied to the shingles, the shingles rotating so that the stain or weather-proofing material will be spread by the centrifugal force to the outer portions of the shingles. In the first of these processes as practiced, it has been necessary for the operator to remove the fastening of the bundle of shingles, lift a portion of that bundle by hand into the vat and then reassemble the shingles and place them simplify on a drying rack or. space where they are permitted to dry. In the second of these practices a very highly volatile coating or treating material is used which is .of course relatively expensive. This drying has taken a considerable length. of time and the shingles are thereupon reassembled and re bundled.

The object of the present invention is to the steps of weather-proofing shingles and more particuarly the weatherproofing of shingles in bundled form. further object is to provide a method of weather-proofing shingles which eflt'ects a much greater production of weather-proofed shingles for a unit of time than possible for the methods heretofore used.

The invention further resides in the steps and series of steps hereinafter described and claimed, reference being made to the accompanying drawings which illustrate a mach ne for practicing our invention, w 1ch machine 59 or apparatus constitutes the subject matter;

of our 00- ending application filed February 10, 1927, erial No. 167 177 of which this is a division.

In the drawings,

Fig. 7 is a sectional elevation of the mount ing for the discharge receiving table.

ig. 8 is a sectional elevation of a portion of the discharge chute and the discharge controlling dam shown in Fig; 5, but on an enlar ed scale.

ig. 9 is a section of a modified form of spray chamber and sprays.

In accordance with the present invention, the method or the steps of the method or process involves the passing of shingles by a coating spray directed substantially at right angles or perpendicular to the face portion or portions of the shingle to be coated; it involves the steps of removing the shin les from a bundle, coating them, and rebund mg them; it involves the steps of removing the A shingles'in layer formation from a bundle,

coating such layer of shingles and then rebnndling the several layers with the indivldual layers being maintained intact; it also in olves the step of drying the treated shingles before such rebundling step sothat when the shingles are rebundled they will be? ready for immediate disposal to the trade.

In the drawings, 10 designates the upper reach and 11 the lower reach of an endless chain conveyor traveling over sprockets 12 and 13, one of which may be driven for effecton the post or standard 15 and the conveyorporting or intermediate sprockets may be in-' eluded in the machine if desired. The sprocket wheel 12 is mounted on a shaft 14 mounted 1011 is arranged to convey the shingles or articles to be treated from the entrance end 0f the machine, shown in Fig. 1 through the sprayin chamber or zone 16, shown'in Fig. 3, and t e drying oven or zone 17, shown in Fig. 3, to the discharge end of the machine which is shown in Fig. 5. 18 designates a table for supporting a bundle of shingles in position at the entrance end of the machine, this table being preferably vertically movable, and to effect this purpose the table is mounted on a plunger 19 movable in the hollow standard 20. This plunger 19 has a stud or roller 21 projecting laterally therefrom out through a slot 22 in the standard 20. The stud or roller 21 engages a cam track 23 which is provided on ratchet wheel 24. As shown, ratchet wheel 24 may be mounted on a shaft 25 carried by the standard 20. The ratchet wheel 24 is preferably provided on its periphery with a series of teeth 26 and as the ratchet wheel is rotated or turned in a clockwise direction, the cam track 23 in engagement with the stud or roller 21 raises the stud or roller. 21, thus raising the plunger 19 and table 18 in accord with the movement of theratchet wheel. This is provided so as to raise the table to position to expose the next succeeding layer of shingles'in the bundle to the action of the conveyor loading mechanism after each layer is removed by the loading mechanism from the table and placed onto the conveyor.

Any suitable'means may be provided for transferring the shingles on the table onto the conveying mechanism. In the form of the invention shown, a reciprocating, suction exerted upon the shingles on the table, This gripping or lifting mechanism is illustrated.-

is, 27 designates the movable loading In t arm which is slidable in a suction pipe28.

This. suction pipe 28 is in communication with asuitable suction pump or the like. The hollow loading arm 27 carries a suction head 29 which is provided with a plurality of apertunes through which the suction influence is lo'adin arm is actuated through means of a pair 0 links 30 which are connected at one end to the suction head 29,-the other-ends of links 30 being pivoted to crankarms 31 carried by sprocket gears 32, of which there are preferably a pair, driven by chains 33 from shaft 14. As the sprocket gears 32 are revolved, the crank arms 31 through means of the links 30 move the suction head 29 and the loading arm 27 back and forth, to and from positions above the loading table and positions above the upper flight of the chain conveyor. 10. .Suitable means are provided for interrupting or breaking the suction influence when the shingles carried by the head '29 moving with the loading arm 27 are carried to position over the conveyor chain 10 so as to discharge the shingles onto the conveyor chain. In the embodiment shown, this is accomplished by providing suction pipe 28 with a valve seat 34 which is adapted to be engaged by the valve or part 35 on the loading arm so as to close the suction pipe and the loading arm to the suction influence when the loading arm reaches the position shown in Fig. 2. Owing to the disposition of the apertures in the suction head and the roughness or unevenness of the shingles, suflicient air is permitted to enter the loading arm from adjacent the surface of the shingles at this point to break the suction, permitting the shingles to drop upon the chain conveyor. After the loading arm has assumed the position shown in Fig. 2 and disposed the shingles upon the chain conveyor, further movement of the sprocket gear 32 results in crank arm 31 and link 30 forcing the loading arm forward to position over the next layer of shingles to betransported into the machine. In assuming such position, the loadin arm actuates mechanism to raise the loa ing table so that the next layer of shingles will be in position to be engaged by the suction head.

of bell crank levers 36 are pivoted as at 37 I to standards 38 at the forward end of the machine. Each carries a link 39 disposed in position to be engaged by one of a pair of contact members .40 mounted on the suction head. Movement of the suction head toward the position shown in Fig. 1 moves the bell cranks from the position shown in Fig. 2 to the position shown in Fig. 1. Each bell crank carries a pawl 41 which engages with the teeth of the ratchet wheel,'moving the ratchet wheel in a clockwise direction one notch as the loading arm moves to its forward position shown in Fig. 1. 42 designates a spring for urging the bell crank lever to the position shown in Fig. 2, where it may be acted upon by the suction head, and 43 designates a locking dog for preventing the return movement of the ratchet Wheel.

The shingles to be treated move upon the endless chain conveyor to the spraying chamber or zone 16. This spraying chamber or zone has a hood 44 and a plurality of spray nozzles 45. The spray nozzles 45, a pair of which are shown in Fig. 4, are positioned so as to spray a portion of one surface of each with the weather-proofing material.

The spraying nozzles for spraying the faces of the shingles are positioned and designed for spraying substantially one half of one face of the shingle as that is the portion of the shingle exposed to the weather when the upon the shingle and the retention of it thereon. This is accentuated by the fact that the shingles pass almost immediately into the drying zone or oven where the weather-proofing material is dried. 47 designates a drip pan to receive the excess weather-proofing material sprayed. The shingles pass on the conveyor from the spray zone into the drier 17. This drier 17 encloses or houses the conveyor tracksand is of sufiicient length to effect a substantial drying of the weatherproofing material on the-shingles while they are passing therethrough and may be of any suitable or desired form. In the embodiment shown, heated air is forced by, means of a suitable blower or the like (not shown) through pipe 48 and passes forward through the drying chamber counter-current to the motion of the shingles, the cooled air being exhausted through pipe 4-9. 4

After passing through the drying zone, the chain conveyor carries the shingles to the discharge end of the machine where they are restacked or bundled. At the discharge end of the machine there is provided a discharge slideway or skid 50 which is supported in position to' receive the shingles as they fall off of the end of the chain conveyor. From this slideway or skid the shingles are distributed in layers upon a stacking platform or table to their original bundled form.

51 designates a stacking or bundling table.

- This table is preferably mounted so as to move vertically with respect to the slideway 50. F or this purpose it is supported by a plunger 52 which moves in a'hollow standard 53. This standard 53 is mounted on one of the frame members 54 of the machine, which is supported by the posts or standards 55. The plunger 52 has a stud or roller 56 projecting laterally therefrom through a slot 57 in the standard 53. This stud or roller is adapted to be engaged by a cam track 58 carried by ratchet wheel 59. As the ratchet wheel 59 is turned in a counter-clockwise direction from the position shown in Fig. 5, the 'cam track 58 acting upon stud or roller 56, lowers the plunger 52 and the table 51. 60 designates a spring for normally urging the plunger 52 and the table 51 towards its uppermost position. The ratchet wheel 59 is mounted on a shaft 61 suitably supported by the brackets or hangers 62 from the frame of the machine. 63 designates a locking dog for preventing return movement of the ratchet wheel. The discharge-receiving table 51 is preferably movable longitudinally of the machine from the position shown in Fig. 5 where it is beneath the slideway 50, through positions where it projects more or less rear- ,wardly beyond slideway 50, to a position where it projects entirely beyond that slideway. This is for laying the shingles one at a time in layer form on the stacking table 51. To achieve this a chain 64 drives a sprocket gear 65. This sprocket gear 65 carries a crank 66 having a lug 67 7 adapted to engage a link 68. This link 68 is counterweighted through means of a weight 69 and as the crank 66 moves in a clockwise direction, as indicated in Fig. 5, thelink 68 is caused to move toward the rear of the machine. This link 68 is connected by means of a stud 69 Fig. 6 where it is beyond the slideway and in I position to receive the shingles. As the stacking table moves rearwardly the ratchet wheel 59 passes over a spring-pressed pawl 72 and upon return movement of the table and ratchet wheel, the abrupt faces of the teeth of the ratchet wheel engaging the pawl 72,

the ratchet wheel is turned one notch, thus lowering the stacking table one position. In order to prevent t charged onto the stacking table when the stacking table. is not in position to receive them, a dam or suitable member 73 is provided. This member extends across the slideway and consists of a stop member proper 74, adapted to be moved by one or more levers 75. These levers are mounted on brackets or bearings 76 and terminate at their lowermost extremities preferably in rollers 77. The upper part of the stacking table 1s provided with a cam member 78 which engages the roller 77, whereby when the table is moved rearwardly, the stop member 7 4 1s caused to move from the position shown in Fig. 5 to the position shown in-Fig. 6, wherein the shingles may pass beneath it and discharge to the stacking table. It is understood, of course, that from the position shown in Fig. 5 the stacking table moves to the position shown in and link 68 causes the table to return to its e shingles being disand spray devices shown inFig. 9, provision is made for coating the entire shingle more or less. In this form it is contemplated that the shingles will be spread apart instead of overlapping, as shown in Fig. 4:, and that a heavy coat of weather-proofing material will be provided on approximately one half of one face and the butts of the shingles, and the remaining portions of the shingles will be given a relatively light coating of weatherproofing material. This will result in any portions of the shingles which might be exposed, due to shrinkage of abutting shingles, leaving spaces or cracks between adjacent edges of the shingles, being protected from the effects; of the weather.

The light coating of Weather-proofing material does not need to be of expensive material-and the portion of the shingle normally exposed to the weather is provided as referred to hereinabove with the heavy weather coating. In this form, 77 designates the spray devices which are preferably of such form and so supplied as to supply a relatively heavy coating of weather-proofing material to the portions of the shingle which they treat, and 78 designates a pair of spray nozzles or devices for supplying a relatively light coating of material to the remaining portions of the faces of the shingles which are uppermost at this point. 79 designates spray nozzles or means for applying a relatively light coating of weather-proofing material to the under side of the shingles, and 80 designates spray nozzles or means for applying a coating of weather-proofing material to the butts of the shingles.

. In operation a bundle of shingles is placed on the table 18 with the shingles disposed fiatwise or horizontally, the straps or ties are removedfrom the bundle leaving the shin; gles so that they may be separated one by one from the bundle. The machine being put into operation the suction head 29 engages the uppermost layer or course of shingles and moves them onto the chain conveyor. The loading arm and suction head then returns to position to engage the next succeeding layer of shingles, in which return movement the loading table is moved upwardly one notch to present the next layer of shingles to the action of the suction head of the loading arm. The shingles move through the machine on the endless chain, passing under the spraying or treating device, where they are sprayed or treated, and then into the dr ing zone or oven, where they are dried. rom

that point they proceed to the discharge end of the machine, where as described in detail hereinabove they are stacked on the discharge receiving table. When a complete bundle of shingles is run through the machine and is stacked on the discharge receiving table, the straps are replaced on the bundle and it is ready for shipment to the purchaser.

The device" may be used for articles other than shingles, and the following claims are not therefore limited in scope to the treatmentzontal plane with a portion of the faces of the shingles overlapping, and directing a spray of treating liquid against the exposed face of each shingle.

3. The method of handling and treating shingles which comprises automatically. transferring successive layers of shingles from a bundle thereof to a conveyor and arranging them thereon in substantially the same horizontal plane, and transporting the shingles thus arranged successively through a water-proofing environment and a drying.

environment in timed relation to the transfer of said shingles from said bundle to said conveyor.

4. The method of treating shingles which comprises automatically transferring successive layers of shingles from a bundle thereof to a conveyor and arranging them thereon in substantially the same horizontal plane, transporting the shingles thus arranged successively through a plurality of treating zones, directing a spray of water-proofing compound against said shingles during the movement thereof through one of said zones, directing a jet of a drying medium against said shingles during their movement through another of said zones, and re-arranging said shingles in superimposed stacked relation in timed'relation to the transfer of said shingles to said conveyor and the movement thereof through said zones.

5. The method of coating wooden shingles, consisting in feeding the shingles in two parallel rows with the butt ends of one row remote from the butt ends of the companion row and their tapered ends adjacently disposed, then passing the rows of shingles between opposed coating means for coating the outwardly disposed butt ends thereof, and concurrently coating a portion of one face of each shingle.

6. The method of treating wooden shingles which includes transposing a bundle of shingles as it comes from the mill into series form, applying treating fluid to said shingles, drying said shingles, and then re-bundling said shingles.

8. The method of treating wooden shingles. from a layered bundle in which the butt ends are outwardly disposed at opposite sides, which includes intermittently moving the layered bundle of shingles perpendicular to the plane of such shingles, successively translating the layers of shingles laterally and i1 serial form from said bundle along the plane of said shingles with the butt ends of the shingles defining the margins of the row formed by such translation, and then applying a treating fluid to the marginal portions of the row of shingles.

9. The method of treating wooden shingles consisting in directing two sprays at right 0 angles to each other, and moving the shingles flatwise in the plane of one of the nozzles with the butt ends of the shingles disposed in opposition to the specified nozzle.
